HPMA copolymers as surfactants in the preparation of biocompatible nanoparticles for biomedical application.

abstract：:Despite numerous strategies involving dynamic covalent bonds to produce self-healing hydrogels with similar frequency-dependent stiffness to native tissues, it remains challenging to use biologically relevant thiol/disulfide exchange to confer such properties to polymeric networks. Herein, we report a new method based...
